403 in Controller Subdirectory access

In this type of structure I usually use something like this:

Taking advantage of the default controller As Home and the default method index.

Code:

- Controllers
    - Admin
        - Admin (Change to Dashboard)
        - AdminControler
        - Login (Change to Home)
        - SecureThis

In routes:

PHP Code:

$routes->group('admin', ['namespace' => 'App\Controllers\Admin'], function($routes)
{
    $routes->add('/', 'Home::index');
    $routes->add('/dashboard', 'Dashboard::index');
   { ... }
}); 


So your routes would look

Code:

http://mydevsite.vhost/admin/ - To login
http://mydevsite.vhost/admin/dashboard - To after login
http://mydevsite.vhost/admin/* - All after login

I think it becomes more readable. But, just a personal opinion.

Thank you for the opinion, but my problem persist, lets say I change the file name and class (already try many things tough):

Code:

- Controllers
    - Admin
        - AdminControler
        - Home
        - Login

 
the route as your suggestion is set to:

PHP Code:

$routes->group('admin', ['namespace' => 'App\Controllers\Admin'], function($routes) {
    $routes->add('/', 'Admin/Login::index');
    $routes->add("home", "Admin/Home::index");
}); 


the result is:

Code:

http://mydevsite.vhost/admin/ - 403 forbiden
http://mydevsite.vhost/admin/dashboard - working fine To after login

This 403 forbidden is my main problem, I have tried to set:
Redirecting Routes, change file and class name
both not working but if I change the folder name to something else it works, is the name "Admin" cannot be used?
